15thc perception on swallowtail merlons?

[Pierre Dumont Himself]

Now that's what I call a mobilization. 
1. I added the Tacuinum sanitatis manuscripts on page 57: BNF lat. 9333 (Swabia or Upper Rhine, 1445-50), BNF NAL 1673 (Pavia or Milano, around 1400), Bibliothèque de l'Université de Liège, Ms. 1041 (same Visconti circle, 1380-1400), and Biblioteca Casanatense, Ms. 4182 (another Visconti copy, 1390-1400). 
2. Following the discussion in the Weltchronik thread (You are not allowed to view links. Register or Login to view.), I moved the Kassel MS (Theol. 4) from Bavaria to Venice in line with the quoted paper by Hartmut Bozinski. I also added the BSB Cgm 250 (Bavaria or Austria, 1400-1450), the  Zurich Ms. Rh. 15 (Zürich, ca. 1350), and the ÖNB Cod. Ser. nova 2612 (Southwest Germany, 1336, with an Upper Rhenish addendum on You are not allowed to view links. Register or Login to view. from the late 15th century). I did not add the BSB Cgm 7375 in keeping with my principle of not including anything labelled as "middle of the 15th century". According to Rudolf Kilian Weigand, the manuscript may have been commissioned by Caspar von Gufidaun, judging by the coat of arms on 62v/63r. This nobleman from South Tyrol was one of the main antagonists of Bishop Nicolaus Cussanus in the 1450s.  As far as I know, he was first recorded in 1438 and passed away in 1458.

5. Bibliothèque de l'Arsenal, Ms-8536 is labelled as 15th-century. I couldn't a more precise dating, so I cannot add it. 
6. Biblioteca nazionale centrale di Firenze II.II.62 is also from the late 15th century.

7. The oldest known copy of Roberto Valturio's treatise is the Urb.lat.281, dated 11 May 1462. I believe the manuscript you shared might be Padova, Biblioteca Capitolare della Curia Vescovile, D. 11 from 1472.
